Abstract

pneumático, cuja a relação de aspecto h/l é estritamente superior a 0,75, que compreende uma armadura de topo (4) constituída por duas camadas de topo de trabalho (41, 42) de elementos de reforço. de acordo com a invenção, as duas camadas de topo de trabalho (41, 42) estão sós presentes para constituir a armadura de topo (4) em pelo menos 40 % da largura da banda de rodagem (5), o valor absoluto da diferença entre os valores absolutos dos ângulos ¿2 e ¿1 sendo superior a 9º, ¿2 sendo maior do que ¿1 em valor absoluto, o ângulo médio a satisfazendo a relação 14 + 131 * exp(-l/100) < a < 20 + 164 * exp(-l/100), e a razão de utilização do potencial de ruptura f2/fr2 da camada de trabalho (42) que é radialmente a mais exterior sendo inferior a 1/6.
